New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.
VPR Score: 5.5
Synopsis
The remote news service allows plaintext command injection while negotiating an encrypted communications channel.Description
The remote news server contains a software flaw in its STARTTLS implementation that could allow a remote, unauthenticated attacker to inject commands during the plaintext protocol phase that will be executed during the ciphertext protocol phase.Successful exploitation could allow an attacker access to private newsgroups and reveal a user's credentials.
